DYEING MACHINE.

npplcation'i'led July 9, 1925. Serial No. 42,520.v

Uur invention relates to certain improvements in dyeing machinesof the paddle type for dyeing stockings and other loose stock.

@ne object of the invention is to increase the capacity of al machine ofthe above mentioned type by providing a series of vats, which are separated by perforated partitions, and 1n which small batches ofmatcrial are dyed. and by mounting the paddles on a common shaft.

le further object ef the invention is to provide means for circulating the dye liquorfirst in one direction-and then in the opposite direction, the liquor circulating through the series of vats.

ln the accompanying drawings Fig. 1 is a. plan view of our improved dyeing machine;

Fig. 2 is a longitudinal sectional view;

Fig. 3 is an end view; and

Fig. l is a transverse sectional view on the line H, Fig. 2.

rlt'he vat 1 is elongated and has a curved bottom 2.

ln the present instance, the vat is divided by perforated, flanged partitions 3 into four compartments., The bottom of the vat has a depression atth'e centre extending below the partitions, forming an uninterrupted space ll--extending from one end of the vat to the other. In the space/1 are the steam pipes 5 and 6, which enter the vat-at opposite ends, and pass each other at the center, as shown in Fig. 1. The steampipes are perforated to allow steam to escape int-o the vat and heat the dye liquor.

The coloring matter is admitted to the vatJ through small pipes 7, which are coupled to the steam pipes. The small pipes are providedwith funnels 8 and valves 9. The steam pipes have valves 10.

Removable, narrow perforated bottom sections 2a enclose the space occupied by the steam pipes. The feed pipes for the dye are madeoomparatively small so that the dye, which is added from time to time, can percolate slowly into the vat.

The holes in the steam pipes are arranged farther apart in the end compartments than in the intermediate compartments. This, with the overlapping steam pipes. insures even distribution of color during the addition'of dye to the bath and causes the liquorv in each compartment to boil in the same proportion.v

arrangements of Mounted on longitudinal shaft 12, which is supported at the center by a bearing 13 that is mounted on the central partition ofthe vat.

On the shaft 12 arefour paddle wheels 15H one for each vat. Each wheel has solid side members 16 and paddles 17, which are mounted on rods 18 thatextend f'rom one side member to the other. The paddles stop short of the center, as shown clearly in Fig. Il.

Mounted on a bracket 19 at one end of the vat is a reversible electric motor Q0, of any well known type. On the shaft of the motoil is a worm Q1, which meshes with a worm wheel 2;). on a stud 23. On the stud is a gear wheel 2i, which meshes with an intermediate gear wheel :25, also mounted on a. stud E2G. The gear wheel 25 meshes with a gear wheel :2T on the Shaft l2. The gearing is located in an enclosing casing 28, as shown in Fig. 3. Other the driving mechanism can be employed without departing from the essential features of the invention.

By the construction hercinbefore described, the paddles are driven for a given time in one direction, then the motor reverses automatically and drives the paddles in' the opposite direction, causing the dye liquor to eirculate, first in one direction and then in the opposite direction.

A machine of this type is' especially adapted for dyeing stockings and other knit or woven fabrics and wool and fur felts. The stockings 'are placed in bags, or are otherwise arranged in batches, and each compartment of the vat contains a certain number of bags orcbatchcs. As the paddles rotate. the liquor is rotated and the material is agitated and turned so that each article is thoroughly and uniformly dyed.

`We claim: i

1. The combination in a dyeing machine, of a vat; a series of perforated transverse partitions` in the vat forming compartments. said 'athaving a central longitudinal depression at the bottom; a narrow perforated bottom section in each compartment closing the dcpression: steam pipes in the depressed portion of the vat under the perforated bottom sections; a paddle wheel in each compartmentof the vat; and means for rotating said wheels.

L2. The combination in a dyeing machine,

of a vat; arseries of perforated, transverse the vat are bearings 11 for av lli) llt-3 tending past the central partition of the vat; 1

bearings on the vat; a longitudinal Shaft vmounted in the bearings; a series of paddle wheels on the shaft, one paddle Wheel for each compartment; and :L reversible electric motor for driving the shat.

3. The combination in :L dyeing machine, of :t vat; a Series of transiferse, perforated partitions in the vat forming compartments, the partitions stopping short of the bottom of the vat; steam pipeS the vat` and extending under the partitions; removable, perforated bottom sections 'enclosing the spaceoccupied by the pipes; a longitudinal shaft; a series of paddle wheels on the shaft, one for each compertment; and means 20 for rotating the shaft.
